SPF 23

SPF 23

Here’s a scene from early Saturday, before about 20 of us went tubing on Guadalupe River in New Braunfels, TX.

At this point in the day, we’ve just arrived and prepare to get our tubes and ice chests ready to go. Plus, there was plenty of sunscreen application to go around. Speaking of which, I applied some SPF 8 sunscreen but then later applied someone else’s SPF 15 sunscreen. So, does that mean I wound up with SPF 23? Or, did I just add 7 more SPF’s?
